controller 10 controls thesensor 4 by executing thecontrol program 9A to implement the function of detecting a substance contained in a gas, for example. - In the present embodiment, the
face 41 is provided with anopening 41 a and anopening 41 b. The opening 41 a is provided to capture a voice of the user during a phone call. Theopening 41 b is provided to output a voice of a call partner to the outside during the phone call. Therefore, the opening 41 a and theopening 41 b are provided such that one of them is provided in one end of theface 41 and the other one is provided in the other end thereof, so that the opening 41 a is located near a user's mouth and theopening 41 b is located near a user's ear during the phone call. - The
receiver 7 is provided inside theopening 41 b. Thereceiver 7 is provided in a direction in which a voice to be output is discharged to the outside through theopening 41 b. - The
sensor 4 and themicrophone 8 are closely provided inside the opening 41 a. Thesensor 4 is provided in a direction in which a substance contained in a gas introduced from the opening 41 a is adequately detected. Specifically, thesensor 4 is provided in a direction in which a substance contained in the gas introduced in a direction indicated by arrow A2 is adequately detected. Themicrophone 8 is provided in a direction in which a voice transmitted through the opening 41 a is adequately detected. Specifically, themicrophone 8 is provided in a direction in which a voice transmitted in a direction indicated by arrow A1, which is parallel to the arrow A2, is adequately detected. - In this way, the
sensor 4 is provided near themicrophone 8. Furthermore, thesensor 4 and themicrophone 8 are provided at positions opposite to theopening 41 a. Therefore, when the user brings the opening 41 a to a portion near his/her mouth so that themicrophone 8 can easily capture the voice during the phone call, the breath of the user reaches thesensor 4 as well as themicrophone 8. As a result, the substance contained in the breath of the user is detected by thesensor 4. - Based on the configuration, when a phone conversation is performed, the
mobile phone 1A can detect a substance contained in the breath of the user and use the detected substance for various types of determination even if the user does not perform any particular operation other than the operation for making a phone call. In other words, themobile phone 1A can detect a substance contained in the breath of the user in a noninvasive and unconscious manner. - The configuration to obtain the above effects is not limited to the configuration illustrated in
FIG. 1 toFIG. 4 . More generally, to obtain the effects, it is only necessary that thesensor 4 is provided near themicrophone 8. Themicrophone 8 is not necessarily provided to the same face as that of thereceiver 7. - Modes in which the
sensor 4 is provided near themicrophone 8 will be explained below with reference toFIG. 1 toFIG. 4 andFIG. 6 toFIG. 8 .FIG. 6 is a front view of amobile phone 1B according to a first modification.FIG. 7 is a front view of amobile phone 1C according to a second modification.FIG. 8 is a D-D cross section of themobile phone 1C. - The modes in which the
sensor 4 is provided near themicrophone 8 include modes in which thesensor 4 is provided to any one of the faces of the electronic device on the side where themicrophone 8 is provided. The modes in which thesensor 4 is provided on the side where themicrophone 8 is provided include a mode in which thesensor 4 and themicrophone 8 are provided to an inner side of the face as illustrated inFIG. 1 toFIG. 4 . Furthermore, the modes in which thesensor 4 is provided on the side where themicrophone 8 is provided include a mode in which thesensor 4 and themicrophone 8 are provided to an outer side of the face as is themobile phone 1B illustrated inFIG. 6 . - The
microphone 8 may be provided to a face of a substrate stored inside thehousing 40. In this case, the modes in which thesensor 4 is provided on the side where themicrophone 8 is provided include modes in which thesensor 4 is provided to a face of the substrate on the side where themicrophone 8 is provided. When themicrophone 8 is provided to the face of the substrate stored inside thehousing 40, for a face of thehousing 40 opposite to the face of the substrate where themicrophone 8 is provided, an opening is formed at a position on the face of thehousing 40 that faces themicrophone 8. - When the
sensor 4 is provided on the side where themicrophone 8 is provided, thesensor 4 and themicrophone 8 may be arranged so as to be adjacent to each other. A space between thesensor 4 and themicrophone 8 may be or may not be formed. When a space is formed between thesensor 4 and themicrophone 8, a distance between thesensor 4 and themicrophone 8 may be determined according to a sensitivity of thesensor 4. - As already explained, the
microphone 8 may be provided to an end apart from thereceiver 7 in order to facilitate a phone conversation. In this case, the modes in which thesensor 4 is provided near themicrophone 8 include the modes in which thesensor 4 is provided to the end where themicrophone 8 is provided, as illustrated inFIG. 1 toFIG. 4 . Furthermore, the modes, in this case, where thesensor 4 is provided near themicrophone 8 include a mode in which thesensor 4 is provided to another face adjacent to the end where themicrophone 8 is provided as is themobile phone 1C illustrated inFIG. 7 andFIG. 8 . Thesensor 4 may be provided inside an opening 43 a which is provided to another face adjacent to the end where themicrophone 8 is provided. - In the
mobile phone 1C, themicrophone 8 is provided to the end of theface 41, and thesensor 4 is provided to theface 43 adjacent to theface 41 in this end. Even in this mode, the breath of the user during a phone call reaches thesensor 4 as well as themicrophone 8. Particularly, in the case of a comparatively small-sized mobile phone, when the user brings the receiver close to his/her ear in order to listen to the voice of the call partner, the bottom face farthest from the receiver can be located nearest to the user's mouth as is theface 43 of the faces. In this case, by providing thesensor 4 to the bottom face, a substance contained in the breath of the user can be effectively detected during the phone call. - When the
sensor 4 is configured by combining a plurality of different sensors, thesensor 4 may be provided so that a less sensitive sensor is provided closer to themicrophone 8. By providing the sensors in this way, the respective sensors can appropriately detect a substance contained in the breath produced when the user outputs a voice toward themicrophone 8. - As explained above, in
Embodiment 1, thesensor 4 for detecting a substance contained in the gas is provided to a position that the breath of the user reaches during the phone call. Therefore, the electronic device according to the present embodiment can detect a substance contained in the breath of the user in a noninvasive and unconscious manner during the phone call. - A configuration of a
mobile phone 1D according toEmbodiment 2 will be explained below with reference toFIG. 9 toFIG. 14 .FIG. 9 is a front view of themobile phone 1D.FIG. 10 is a back view of themobile phone 1D.FIG. 11 is an E-E cross section of themobile phone 1D.FIG. 12 is an F-F cross section of themobile phone 1D.FIG. 13 is a G-G cross section of themobile phone 1D.FIG. 14 is a block diagram of themobile phone 1D. In the following explanation, the same reference signs as these used for the already explained portions may be assigned to portions the same as the already explained portions. In the following explanation, explanation overlapping the already explained one may be omitted. - As illustrated in
FIG. 9 toFIG. 14 , themobile phone 1D includes thetouch screen display 2, thebutton 3, asensor 4 a, a sensor (second sensor) 4 b, thecommunication unit 6, thereceiver 7, a microphone (sound input unit) 8 a, a microphone (sound input unit) 8 b, thestorage 9, thecontroller 10, and thehousing 40. - The
sensors sensor 4. That is, thesensors microphones microphone 8. That is, themicrophones - The
face 41 of thehousing 40 is provided with the opening 41 a and theopening 41 b. The opening 41 a is provided to capture a voice of the user during a phone call. Theopening 41 b is provided to output a voice of the call partner to the outside during the phone call. Therefore, the opening 41 a and theopening 41 b are provided such that one of them is provided in one end of theface 41 and the other one is provided in the other end thereof, so that the opening 41 a is located near the user's mouth and theopening 41 b is located near a user's ear during the phone call. - The
receiver 7 is provided inside theopening 41 b. Thereceiver 7 is provided in a direction in which a voice to be output is discharged to the outside through theopening 41 b. - The
sensor 4 a and themicrophone 8 a are closely provided inside the opening 41 a. Thesensor 4 a is provided in a direction in which a substance contained in the gas introduced from the opening 41 a is adequately detected. Specifically, thesensor 4 a is provided in a direction in which a substance contained in the gas introduced in the direction indicated by the arrow A2 is adequately detected. Themicrophone 8 a is provided in a direction in which a voice transmitted through the opening 41 a is adequately detected. Specifically, themicrophone 8 a is provided in a direction in which a voice transmitted in a direction indicated by the arrow A1, which is parallel to the arrow A2, is adequately detected. - The
housing 40 has aface 46 on the opposite side of theface 41. Theface 46 is provided with anopening 46 a. In the following explanation, theface 41 may be called a front face and theface 46 may be called a back face. The opening 46 a is provided to a position less likely to be covered by the hand holding themobile phone 1D during a phone call. - A
sensor 4 b and amicrophone 8 b are closely provided inside the opening 46 a. Thesensor 4 b is provided in a direction in which a substance contained in the gas introduced from the opening 46 a is adequately detected. Specifically, thesensor 4 b is provided in a direction in which a substance contained in the gas introduced in the direction indicated by arrow A4 is adequately detected. Themicrophone 8 b is provided in a direction in which a voice transmitted through the opening 46 a is adequately detected. Specifically, themicrophone 8 b is provided in a direction in which a voice transmitted in a direction indicated by arrow A3, which is parallel to the arrow A4, is adequately detected. - The
microphone 8 b is used to acquire sounds around themobile phone 1D during a phone call. Thecontroller 10 uses the sounds acquired by themicrophone 8 b for noise cancellation. Specifically, thecontroller 10 inverses a sound signal input through themicrophone 8 b and superimposes the inverted sound signal on a sound signal input through themicrophone 8 a during the phone call. Such a control allows removal of components of the sounds around themobile phone 1D from the sound signal transmitted to the call partner. - The
sensor 4 b is used to detect a substance contained in the gas around themobile phone 1D. Thecontroller 10 uses a detection result of thesensor 4 b to remove influence of the substance contained in the gas around themobile phone 1D from a detection result of thesensor 4 a. Specifically, thecontroller 10 determines the concentration or the like of the substance contained in the breath of the user, during the phone call, based on a value obtained by subtracting a detected value of thesensor 4 b from a detected value of thesensor 4 a. - How to detect a substance according to
Embodiment 2 will be explained in more detail below with reference toFIG. 15 .FIG. 15 is a diagram of a detection example of a certain substance (hereinafter, “substance A”) contained in a gas. When thecontroller 10 turns on thesensor 4 a at the time of a phone call, a detected value of the substance A indicated by thesensor 4 a changes like, for example, line L1. At this time, thecontroller 10 further turns on thesensor 4 b. When the substance A is originally contained in the gas around themobile phone 1D, a detected value of the substance A indicated by thesensor 4 b changes like, for example, line L2. - The gas in which the substance A is detected by the
sensor 4 a is a gas in which the breath of the user and the gas around themobile phone 1D are mixed. When the substance A is originally contained in a gas (second gas) around themobile phone 1D, the detected value of thesensor 4 a includes the influence of the gas around themobile phone 1D. Therefore, thecontroller 10 subtracts the detected value of thesensor 4 b from the detected value of thesensor 4 a. For example, thecontroller 10 uses a detected value V3, obtained by subtracting a detected value V2 of thesensor 4 b after T0 seconds since turning-on from a detected value V1 of thesensor 4 a after T0 seconds since turning-on, for various types of determination processing, as a concentration of the substance A contained in the breath of the user. In the example illustrated inFIG. 15 , a detected value obtained by subtracting the detected value of thesensor 4 b from the detected value of thesensor 4 a changes like line L3. - A processing procedure of detection processing of a substance according to
Embodiment 2 will be explained below with reference toFIG. 16 .FIG. 16 is a flowchart of a processing procedure of the detection processing of the substance. The processing procedure illustrated inFIG. 16 is executed during a phone call. Thesensors FIG. 16 . When thesensors FIG. 16 is executed for each substance. - At Step S10, the
controller 10 acquires a detected value of thesensor 4 b on the back face side. At Step S20, thecontroller 10 acquires a detected value of thesensor 4 a on the front face side. An execution sequence of Steps S10 and S20 may be reversed. Then, at Step S30, thecontroller 10 subtracts the detected value of thesensor 4 b from the detected value of thesensor 4 a. - In this way, the detection of the substance contained in the gas around the
mobile phone 1D enables the detection accuracy of the substance contained in the breath of the user to be improved. However, during the phone call, the voice uttered by the user causes the substance contained in the breath of the user to spread in the gas around themobile phone 1D. To reduce the influence of such spread, the sensor for detecting a substance contained in the ambient gas may be provided to a face different from the face where the sensor for detecting the substance contained in the breath is provided. Furthermore, as illustrated inFIG. 9 toFIG. 13 , the sensor for detecting a substance contained in the ambient gas may be provided to a face opposite to the face where the sensor for detecting the substance contained in the breath is provided. - The arrangement of the
sensor 4 a and themicrophone 8 a may be appropriately changed as is the arrangement of thesensor 4 and themicrophone 8. Thesensor 4 b does not need to be provided close to themicrophone 8 b. Themobile phone 1D does not need to have a noise cancelling function during a phone call. That is, themobile phone 1D does not have to include themicrophone 8 b. - As explained above, by using the sensors provided to the different faces, it is possible to detect a substance contained in the breath of the user with higher accuracy while maintaining the noninvasive and unconscious manner.
- The embodiments disclosed in the present application can include items obvious to those skilled in the art, and can be modified in a range without departing the gist and the scope of the invention. Furthermore, the embodiments and modifications thereof disclosed in the present application can be appropriately combined with each other. For example, the embodiments may be modified as follows.
- The
sensor 4 may be configured as a component integrated with themicrophone 8. Thesensor 4 a may be configured as a component integrated with themicrophone 8 a. In this way, by configuring the sensor as a component integrated with the microphone, it is ensured that the sensor is provided close to the microphone. Moreover, for example, when a plurality of sensors for respectively detecting specific substances are arranged around the microphone, it is possible to detect various substances contained in the breath during the phone call while saving a space. - The embodiments have explained the examples of detecting substances contained in the breath of the user during the phone call; however, the timing of detecting the substance contained in the breath of the user is not limited thereto. The timing of detecting each substance contained in the breath of the user by using a sensor provided near the microphone has only to be a timing when the user outputs a voice near the microphone. Examples of the timing when the user outputs a voice near the microphone include a timing when an instruction is issued by voice input and a timing when a voice is recorded.
- Recently, research and development to apply a technology of measuring a causative substance of odor to various industrial fields have been advanced, and practical use of the technology is already started in many industrial fields. For example,
Patent Literature 2 discloses a system for measuring an amount of alcohol contained in a breath of a user by using a device connected to a mobile phone carried by the user for the purpose of preventing drunk driving. In a medical field, a device or the like for detecting the presence of Helicobacter pylori based on the concentration of carbon dioxide contained in the breath is put into the practical use. - Incidentally, a wide variety of functions are provided in a mobile phone, and power consumption associated with the functions becomes a problem. If a function of measuring a causative substance of odor or the like as data for the user is provided in a mobile phone, a system of acquiring measurement data while achieving power saving is required.
- For the foregoing reasons, there is a need for an electronic device, a control method, and a control program capable of reducing, as much as possible, the power consumed when the data for the user is measured.
- A physical configuration of a mobile phone according to an embodiment explained below will be explained with reference to
FIG. 17 toFIG. 20 .FIG. 17 is a front view of amobile phone 1 according toEmbodiment 3.FIG. 18 is an H-H cross section of themobile phone 1 according toEmbodiment 3.FIG. 19 is an I-I cross section of themobile phone 1 according toEmbodiment 3.FIG. 20 is a J-J cross section of themobile phone 1 according toEmbodiment 3. - As illustrated in
FIG. 17 toFIG. 20 , themobile phone 1 includes thehousing 40. Thehousing 40 has thefaces 41 to 46, and various components are supported by the inner sides and the outer sides of the faces. Theface 41 of themobile phone 1 is provided with the opening 41 a and theopening 41 b. The opening 41 a is provided to capture a voice of the user during a phone call. Theopening 41 b is provided to output a voice of the call partner to the outside during the phone call. Therefore, the opening 41 a and theopening 41 b are provided such that one of them is provided in one end of theface 41 and the other one is provided in the other end thereof, so that the opening 41 a is located near the user's mouth and theopening 41 b is located near a user's ear during the phone call. - A
speaker 11 is provided inside theopening 41 b. Thespeaker 11 is provided in a direction in which a voice to be output is discharged to the outside through theopening 41 b. Thespeaker 11 may be called a receiver when it is mainly used for outputting the voice during the phone call. - An
olfactory sensor 4 c and themicrophone 8 are closely provided inside the opening 41 a, as illustrated in, for example,FIG. 20 . Theolfactory sensor 4 c is provided in a direction in which a substance contained in the gas introduced from the opening 41 a is adequately detected. Specifically, as illustrated inFIG. 19 andFIG. 20 , theolfactory sensor 4 c is provided in a direction in which a substance contained in the gas introduced in a direction indicated by arrow A2 is adequately detected. Themicrophone 8 is provided in a direction in which a voice transmitted through the opening 41 a is adequately detected. Specifically, as illustrated inFIG. 18 andFIG. 20 , themicrophone 8 is provided in a direction in which a voice transmitted in a direction indicated by the arrow A1, which is parallel to the arrow A2, is adequately detected. - In this way, the
olfactory sensor 4 c is provided near themicrophone 8. Furthermore, theolfactory sensor 4 c and themicrophone 8 are provided at positions opposite to theopening 41 a. Therefore, when the user brings the opening 41 a to a portion near his/her mouth so that themicrophone 8 can easily capture the voice during the phone call, the breath of the user reaches theolfactory sensor 4 c as well as themicrophone 8. As a result, the substance contained in the breath of the user is detected by theolfactory sensor 4 c. - Based on the configuration, when a phone call is made, the
mobile phone 1 can detect a substance contained in the breath of the user and use the detected substance for various types of determination even if the user does not perform any particular operation other than the operation for making a phone call. In other words, themobile phone 1 can detect a substance contained in the breath of the user in a noninvasive and unconscious manner. - The configuration to obtain the above effects is not limited to the configuration illustrated in
FIG. 17 toFIG. 20 . More generally, it is only necessary that at least theolfactory sensor 4 c is provided near themicrophone 8. - A functional configuration of the mobile phone according to
Embodiment 3 will be explained with reference toFIG. 21 .FIG. 21 is a block diagram of the mobile phone according toEmbodiment 3. As illustrated inFIG. 21 , themobile phone 1 includes adisplay 20, thebuttons 3, theolfactory sensor 4 c, aproximity sensor 5, thecommunication unit 6, themicrophone 8, thestorage 9, thecontroller 10, thespeaker 11, acamera 12, anattitude detection unit 15, avibrator 18, anillumination sensor 19, and atouch screen 21. - The
display 20 is provided with a display device such as a liquid crystal display (LCD), an organic electroluminescence display (GELD), or an inorganic electroluminescence display (IELD). The display 22 displays text, images, symbols, graphics, and the like. - The
buttons 3 accept an operation input by a user. The number of thebuttons 3 may be single or plural. - The
illumination sensor 19 detects illuminance of the ambient light of themobile phone 1. The illuminance indicates intensity of light, lightness, or brightness. Theillumination sensor 19 is used, for example, to adjust the brightness of thedisplay 20. - The
proximity sensor 5 detects the presence of a nearby object without any physical contact. Theproximity sensor 5 detects the presence of the object based on a change of the magnetic field, a change of the return time of the reflected ultrasonic wave, etc. Theproximity sensor 5 detects that, for example, thedisplay 20 is brought close to someone's face. Theillumination sensor 19 and theproximity sensor 5 may be configured as one sensor. Theillumination sensor 19 can be used as a proximity sensor. - The
communication unit 6 performs communication via radio waves. A communication system supported by thecommunication unit 6 is wireless communication standard. The wireless communication standard includes, for example, a communication standard of cellar phones such as 2G, 3G, and 4G. The communication standard of cellar phones includes, for example, Long Term Evolution (LTE), Wideband Code Division Multiple Access (W-CDMA), CDMA 2000, a Personal Digital Cellular (PDC), a Global System for Mobile Communications (GSM), and a Personal Handy-phone System (PHS). The wireless communication standard further includes, for example, Worldwide Interoperability for Microwave Access (WiMAX), IEEE 802.11, Bluetooth, Infrared Data Association (IrDA), and Near Field Communication (NFC), and Wireless Personal Area network (WPAN). The communication standard of WPAN includes, for example, ZigBee. Thecommunication unit 6 may support one or more communication standards. - The
olfactory sensor 4 c detects a substance contained in a gas. For example, theolfactory sensor 4 c measures a concentration of a specific substance contained in a gas. Theolfactory sensor 4 c is also called an odor sensor or an exhalation sensor. Examples of a substance detected by theolfactory sensor 4 c include various chemical substances. Examples of a substance detected by theolfactory sensor 4 c includes a substance used for, for example, the determination of a degree of bad breath, the determination of drinking, the diagnosis of stress, the early detection of a disease such as a cancer, etc. The substance detected by theolfactory sensor 4 c may be a substance that cannot be detected via olfaction by human beings but can be detected via olfaction by, for example, a dog. Theolfactory sensor 4 c may be configured to detect a plurality of substances in a selective manner. Theolfactory sensor 4 c may transmit a detection result of the substance contained in the gas to thecontroller 10 or may transmit measurement data such as the concentration of the specific substance contained in the gas to thecontroller 10. When the configuration is such that the measurement data is transmitted from theolfactory sensor 4 c to thecontroller 10, thecontroller 10 detects and determines the substance. - The
olfactory sensor 4 c may be a Surface Acoustic Wave (SAW) device. The SAW device has an advantage in power saving and high-integration, and is therefore favorable to be provided to a mobile phone that operates by a battery and the downsizing of which is demanded. - The
microphone 8 is a sound input unit. Themicrophone 8 converts an input sound into an electric signal, and transmits the electric sound to thecontroller 10. When a voice produced by a user is input, for example, during phone call, themicrophone 8 transmits a sound pressure level of a sound signal to thecontroller 10. - The
storage 9 stores therein programs and data. Thestorage 9 is used also as a work area that temporarily stores a processing result of thecontroller 10. Thestorage 9 may include any non-transitory storage medium such as a semiconductor storage medium and a magnetic storage medium. Thestorage 9 may include a plurality type of storage mediums. Thestorage 9 may include a combination of a portable storage medium such as a memory card, an optical disc, or a magneto-optical disc with a reader of the storage medium. Thestorage 9 may include a storage device used as a temporary storage area such as Random Access Memory (RAM). - Programs stored in the
storage 9 include applications executed in the foreground or the background and a control program for assisting operations of the applications. The application causes thecontroller 10, for example, to display a screen on thedisplay 20 and perform a process according to a gesture detected through thetouch screen 21. The control program is, for example, an OS. The applications and the control program may be installed in thestorage 9 through wireless communication by thecommunication unit 6 or through a non-transitory storage medium. - The
storage 9 stores therein acontrol program 9A, aphone call application 9C, and settingdata 9Z, for example. Thephone call application 9C provides a call function for making calls by wireless communication. The settingdata 9Z includes information about various settings and various types of processing related to the operation of themobile phone 1. For example, the settingdata 9Z includes olfactory sensor management information for managing whether theolfactory sensor 4 c is active or not. - The
control program 9A provides functions about various types of control for operating themobile phone 1. Thecontrol program 9A achieves making calls by controlling thecommunication unit 6, themicrophone 8, and the like, for example. The functions provided by thecontrol program 9A may be used by being combined with functions provided by another program such as thephone call application 9C in some cases. - Furthermore, the
control program 9A includes a function of activating theolfactory sensor 4 c when the phone call function is in execution. When at least a function provided by thephone call application 9C is executed, it is determined that the phone call function is in execution. Examples of the state in which the function provided by thephone call application 9C is executed include a state in which a user interface used to perform an operation for a phone call is displayed on thedisplay 20 in association with an operation of the user. Examples of the state in which the function provided by thephone call application 9C is executed include a state in which an incoming call screen for informing the user of an incoming call is displayed on thedisplay 20. Examples of the state in which the function provided by thephone call application 9C is executed include a state from when processing for a phone call is started through a telephone connection established in association with an outgoing call operation performed by the user on the user interface to when the processing for the phone call is terminated. Examples of the state in which the function provided by thephone call application 9C is executed include a state from when the processing for a phone call is started through a telephone connection established in association with an incoming-call response operation performed by the user on the incoming call screen to when the processing for the phone call is terminated. Examples of the case in which the processing for the phone call is terminated include a case in which a call ending operation is performed by the user, a case in which the telephone connection is released by the call partner (phone conversation is terminated by the call partner), a case in which the telephone connection is disconnected, etc. The execution of thephone call application 9C may be stopped in response to the termination of the processing for the phone call. Alternatively, the execution of thephone call application 9C may be continued even when the processing for the phone call is terminated. In this case, the execution of thephone call application 9C is stopped by an operation for terminating thephone call application 9C such as an end operation (deletion from thedisplay 20, etc.) of the user interface used to perform an operation for a phone call. - The
controller 10 is a processing unit. Examples of the processing units include, but are not limited to, a Central Processing Unit (CPU), System-on-a-chip (SoC), a Micro Control Unit (MCU), and a Field-Programmable Gate Array (FPGA). Thecontroller 10 integrally controls the operations of themobile phone 1 to implement various functions. - Specifically, the
controller 10 executes instructions contained in the program stored in thestorage 9 while referring to the data stored in thestorage 9 as necessary. Thecontroller 10 controls a function unit according to the data and the instructions to thereby implement the various functions. Examples of the function unit include, but are not limited to, thedisplay 20, thecommunication unit 6, themicrophone 8, thespeaker 11, and thevibrator 18. Thecontroller 10 can change the control according to the detection result of a detector. Examples of the detectors include, but are not limited to, thebuttons 3, theillumination sensor 19, theproximity sensor 5, theolfactory sensor 4 c, thecamera 12, theattitude detection unit 15, and thetouch screen 21. - When the phone call function is in execution, the
controller 10 activates theolfactory sensor 4 c by executing thecontrol program 9A, for example. When at least the function provided by thephone call application 9C is in execution, thecontroller 10 determines that the phone call function is in execution. For example, when the user interface used to perform an operation for a phone call is displayed on thedisplay 20, thecontroller 10 determines that the phone call function is in execution. For example, when the incoming call screen for informing the user of an incoming call is displayed on thedisplay 20, thecontroller 10 determines that the phone call function is in execution. For example, thecontroller 10 determines that the phone call function is in execution during a period of time from when the processing for a phone call is started through a telephone connection established in association with an outgoing call operation performed by the user on the user interface to when the processing for the phone call is terminated. For example, thecontroller 10 determines that the phone call function is in execution during a period of time from when the processing for a phone call is started through a telephone connection established in association with an incoming-call response operation performed by the user on the incoming call screen to when the processing for the phone call is terminated. When the processing for the phone call is terminated, thecontroller 10 determines that the execution of thephone call application 9C is also stopped. Examples of the case in which the processing for the phone call is terminated include a case in which a call ending operation is performed by the user, a case in which the telephone connection is released by the call partner (phone conversation is terminated by the call partner), a case in which the telephone connection is disconnected, etc. Even when the processing for the phone call is terminated, thecontroller 10 may determine that the phone call function is in execution until an end operation or the like (deletion from thedisplay 20, etc.) of the user interface used to perform an operation for a phone call is performed. - In the present application, examples of activating a computer program (or application) by the
controller 10 include: reading newly the computer program stored in thestorage 9 and starting the process thereof; and starting newly the process of a computer program that has already been read. In the present application, examples of executing a computer program by thecontroller 10 include: activating the computer program; resuming the computer program that is currently suspended; and continuing the process of the computer program that has been activated. - Part or all of the programs and the data stored in the
storage 9 inFIG. 21 may be downloaded from any other device through wireless communication by thecommunication unit 6. Part or all of the programs and the data stored in thestorage 9 inFIG. 21 may be stored in the non-transitory storage medium that can be read by the reader included in thestorage 9. Examples of the non-transitory storage mediums include, but are not limited to, an optical disc such as CD, DVD, and Blu-ray, a magneto-optical disc, magnetic storage medium, a memory card, and solid-state storage medium. - The
speaker 11 is a sound output unit that outputs a sound. The speaker is a dynamic speaker, for example, which transmits a sound converted from an electric signal to a user and so on. The speaker 22 is used to output a voice of a phone call, or a sound of music contents or moving image contents, for example. Thespeaker 11 is called a receiver in some times when it is used mainly for outputting a voice of a phone call. - The
camera 12 is an in-camera for photographing an object facing thedisplay 20. Thecamera 12 converts a photographed image to electric signals. Themobile phone 1 may include an out-camera for photographing an object facing the other side of thedisplay 20 in addition to thecamera 12. - The
attitude detection unit 12 detects attitude of themobile phone 1. Theattitude detection unit 12 includes at least one of an acceleration sensor, direction sensor, and gyroscope to detect the attitude. - The
vibrator 18 vibrates part or the whole of themobile phone 1. The vibrator includes a piezoelectric element, an eccentric motor, or the like to generate vibration, for example. The vibration generated by thevibrator 18 is used not to transmit sounds but to notify a user of a various type of events such as an incoming call. - The
touch screen 21 detects contact with thetouch screen 21. The touch screen is used to detect a contact operation by a user with a finger, a pen, a stylus pen, or the like. Examples of the gesture detected via thetouch screen 21 include, but are not limited to, a touch, a long touch, a release, a swipe, a tap, a double-tap, a long tap, a drag, a flick, a pinch-in, and a pinch-out. Any technology such as capacitive sensing, resistive sensing, surface acoustic wave (or ultrasonic) sensing, infrared sensing, electromagnetic induction sensing, and load sensing, may be used to allow thetouch screen 21 to detect contact. - The functional configuration of the
mobile phone 1 illustrated inFIG. 21 is only an example, and therefore it can be modified as required within a scope that does not depart from the gist of the present invention. For example, themobile phone 1 may not be provided with theattitude detection unit 15 and thetouch screen 21. - An example of a processing procedure of the
mobile phone 1 according toEmbodiment 3 will be explained below with reference toFIG. 22 .FIG. 22 is a diagram of an example of the processing procedure by the mobile phone according toEmbodiment 3. The processing procedure illustrated inFIG. 22 is implemented by thecontroller 10 executing thecontrol program 9A and the like stored in thestorage 9. The processing procedure illustrated inFIG. 22 is repeatedly performed by thecontroller 10 while themobile phone 1 operates. - As illustrated in
FIG. 22 , at Step S101, thecontroller 10 determines whether thephone call application 9C is in execution. When the function provided by thephone call application 9C is in execution, thecontroller 10 determines that thephone call application 9C is in execution. Examples of the case in which the function provided by thephone call application 9C is in execution include a state in which the user interface used to perform an operation for a phone call is displayed on thedisplay 20 in association with a user operation. Furthermore, examples of the state in which the function provided by thephone call application 9C is executed include a state in which the incoming call screen for informing the user of an incoming call is displayed on thedisplay 20. Moreover, examples of the state in which the function provided by thephone call application 9C is executed include a state from when the processing for a phone call is started through a telephone connection established in association with an outgoing call operation performed by the user on the user interface to when the processing for the phone call is terminated. Furthermore, examples of the state in which the function provided by thephone call application 9C is executed include a state from when the processing for a phone call is started through a telephone connection established in association with an incoming-call response operation performed by the user on the incoming call screen to when the processing for the phone call is terminated. - When the
phone call application 9C is in execution as a result of determination (Yes at Step S101), then at Step S102, thecontroller 10 determines whether theolfactory sensor 4 c is inactive. - When the
olfactory sensor 4 c is inactive as a result of determination (Yes at Step S102), then at Step S103, thecontroller 10 activates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 22 . Meanwhile, when theolfactory sensor 4 c is not inactive (i.e. when it is active) as a result of determination (No at Step S102), thecontroller 10 directly ends the processing procedure illustrated inFIG. 22 . - When the
phone call application 9C is not in execution as a result of determination at Step S101 (No at Step S101), then at Step S104, thecontroller 10 determines whether theolfactory sensor 4 c is active. - When the
olfactory sensor 4 c is active as a result of determination (Yes at Step S104), then at Step S105, thecontroller 10 inactivates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 22 . Meanwhile, when theolfactory sensor 4 c is not active (i.e. when it is inactive) as a result of determination (No at Step S104), thecontroller 10 directly ends the processing procedure illustrated inFIG. 22 . -
FIG. 23 is a diagram of a relationship between an execution state of the phone call application according toEmbodiment 3 and an operation state of the olfactory sensor. According to the processing procedure illustrated inFIG. 22 , as illustrated inFIG. 23 , when thephone call application 9C activated in response to, for example, a user operation or an incoming call is in execution, themobile phone 1 operates (activates) theolfactory sensor 4 c. Meanwhile, when thephone call application 9C is stopped, themobile phone 1 does not operate (inactivates) theolfactory sensor 4 c. Therefore, according toEmbodiment 3, the power consumed by theolfactory sensor 4 c when data for the user is measured can be reduced as much as possible. Moreover, according toEmbodiment 3, when a target to be measured by theolfactory sensor 4 c is, for example, a concentration of the specific substance contained in the breath of the user, measurement data can be effectively acquired. -
Embodiment 4 will explain an example of activating theolfactory sensor 4 c when an outgoing call operation is performed by the user. A functional configuration of a mobile phone according toEmbodiment 4 is basically the same as that ofEmbodiment 3 but some points described below are different. - The
control program 9A includes a function of activating theolfactory sensor 4 c when the outgoing call operation is performed. Examples of the outgoing call operation include an operation using thebutton 3. Examples of the outgoing call operation include an operation performed by the user to make an outgoing call on the user interface used to perform an operation for a phone call. The operation performed by the user on the user interface used to perform an operation for a phone call is determined based on the detection result of thetouch screen 21. - The
controller 10 activates theolfactory sensor 4 c by executing, for example, thecontrol program 9A when the outgoing call operation is performed. - An example of a processing procedure of the
mobile phone 1 according toEmbodiment 4 will be explained below with reference toFIG. 24 .FIG. 24 is a diagram of an example of the processing procedure by the mobile phone according toEmbodiment 4. The processing procedure illustrated inFIG. 24 is implemented by thecontroller 10 executing thecontrol program 9A or the like stored in thestorage 9. The processing procedure illustrated inFIG. 24 is repeatedly performed by thecontroller 10 while themobile phone 1 operates. - As illustrated in
FIG. 24 , at Step S201, thecontroller 10 determines whether thephone call application 9C is in execution. - When the
phone call application 9C is in execution as a result of determination (Yes at Step S201), then at Step S202, thecontroller 10 determines whether the outgoing call operation has been performed. When the outgoing call operation has been performed as a result of determination (Yes at Step S202), then at Step S203, thecontroller 10 determines whether theolfactory sensor 4 c is inactive. - When the
olfactory sensor 4 c is inactive as a result of determination (Yes at Step S203), then at Step S204, thecontroller 10 activates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 24 . Meanwhile, when theolfactory sensor 4 c is not inactive (i.e. when it is active) as a result of determination (No at Step S203), thecontroller 10 directly ends the processing procedure illustrated inFIG. 24 . - When the outgoing call operation is not performed as a result of determination at Step S202 (No at Step S202), then at Step S205, the
controller 10 determines whether theolfactory sensor 4 c is active. - When the
olfactory sensor 4 c is active as a result of determination (Yes at Step S205), then at Step S206, thecontroller 10 inactivates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 24 . Meanwhile, when theolfactory sensor 4 c is not active (i.e. when it is inactive) as a result of determination (No at Step S205), thecontroller 10 directly ends the processing procedure illustrated inFIG. 24 . - When the
phone call application 9C is not in execution as a result of determination at Step S201 (No at Step S201), then thecontroller 10 proceeds to Step S205, and determines whether theolfactory sensor 4 c is active. -
FIG. 25 is a diagram of a relationship between an execution state of the phone call application according toEmbodiment 4 and an operation state of the olfactory sensor. According to the processing procedure illustrated inFIG. 24 , as illustrated inFIG. 25 , when thephone call application 9C activated in response to a user operation is in execution, themobile phone 1 starts the operation of theolfactory sensor 4 c at a timing when the outgoing call operation is performed by the user. Themobile phone 1 does not start the operation of theolfactory sensor 4 c even during the execution of thephone call application 9C if the user does not perform an outgoing call operation. Therefore, according toEmbodiment 4, the power consumed by theolfactory sensor 4 c when the data for the user is measured can be reduced more than that of the example illustrated inEmbodiment 3. Moreover, according toEmbodiment 4, when a target to be measured by theolfactory sensor 4 c is, for example, a concentration of the specific substance contained in the breath of the user, measurement data can be more effectively acquired than that of the example illustrated inEmbodiment 3. It is easily assumed that a speech utterance is provided by the user when the outgoing call operation is performed by the user. Based on this assumption, it is considered that, in many cases, the speech utterance is not provided by the user until a phone call is started. Therefore, a case where the operation is started at a timing of the outgoing call operation can reduce a wasteful operation time during which measurement data cannot be obtained, of the operation time of theolfactory sensor 4 c, more than that of the case where theolfactory sensor 4 c is operated during the execution of thephone call application 9C. Thus, the measurement data can be effectively acquired. -
Embodiment 5 will explain an example of activating theolfactory sensor 4 c when a telephone connection is established in response to an outgoing call operation performed by the user.

control program 9A includes a function of activating theolfactory sensor 4 c when a telephone connection is established in response to an outgoing call operation performed by the user. - The
controller 10 activates theolfactory sensor 4 c by executing, for example, thecontrol program 9A when the telephone connection is established in response to the outgoing call operation performed by the user. - An example of a processing procedure of the
mobile phone 1 according toEmbodiment 5 will be explained below with reference toFIG. 26 .FIG. 26 is a diagram of an example of the processing procedure by the mobile phone according toEmbodiment 5. The processing procedure illustrated inFIG. 26 is implemented by thecontroller 10 executing thecontrol program 9A or the like stored in thestorage 9. The processing procedure illustrated inFIG. 26 is repeatedly performed by thecontroller 10 while themobile phone 1 operates. - As illustrated in
FIG. 26 , at Step S301, thecontroller 10 determines whether thephone call application 9C is in execution. - When the
phone call application 9C is in execution as a result of determination (Yes at Step S301), then at Step S302, thecontroller 10 determines whether a telephone connection has been established in response to the outgoing call operation. When the telephone connection has been established in response to the outgoing call operation as a result of determination (Yes at Step S302), then at Step S303, thecontroller 10 determines whether theolfactory sensor 4 c is inactive. - When the
olfactory sensor 4 c is inactive as a result of determination (Yes at Step S303), then at Step S304, thecontroller 10 activates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 26 . Meanwhile, when theolfactory sensor 4 c is not inactive (i.e. when it is active) as a result of determination (No at Step S303), thecontroller 10 directly ends the processing procedure illustrated inFIG. 26 . - When the telephone connection has not been established in response to the outgoing call operation as a result of determination at Step S302 (No at Step S302), then at Step S305, the

FIG. 27 is a diagram of a relationship between an execution state of the phone call application according toEmbodiment 5 and an operation state of the olfactory sensor. According to the processing procedure illustrated inFIG. 26 , as illustrated inFIG. 27 , when thephone call application 9C activated in response to a user operation is in execution, themobile phone 1 starts the operation of theolfactory sensor 4 c at a timing when a telephone connection is established in response to the outgoing call operation performed by the user. Themobile phone 1 does not start the operation of theolfactory sensor 4 c even during the execution of thephone call application 9C if the telephone connection is not established in response to the outgoing call operation performed by the user. Therefore, according toEmbodiment 5, the power consumed by theolfactory sensor 4 c when the data for the user is measured can be further reduced than that of the example illustrated inEmbodiment 4. Moreover, according toEmbodiment 5, when a target to be measured by theolfactory sensor 4 c is, for example, a concentration of the specific substance contained in the breath of the user, measurement data can be more effectively acquired than that of the example illustrated inEmbodiment 4. It is assumed that a speech utterance is often started from the user side when a telephone connection is established in response to the outgoing call operation. Based on this assumption, it is considered that, in many cases, the speech utterance is not provided by the user until the telephone connection is established. Therefore, a case where the operation is started at a timing of the establishment of the telephone connection can reduce the wasteful operation time more than that of the case where theolfactory sensor 4 c is operated at the timing of the outgoing call operation. Thus, the measurement data can be effectively acquired. -
Embodiment 6 will explain an example of activating theolfactory sensor 4 c when a sound pressure level of a sound input to themicrophone 8 reaches a certain value or higher after the establishment of the telephone connection in response to the outgoing call operation performed by the user.

The processing procedure illustrated inFIG. 28 is repeatedly performed by thecontroller 10 while themobile phone 1 operates. - As illustrated in
FIG. 28 , at Step S401, thecontroller 10 determines whether thephone call application 9C is in execution. - When the
phone call application 9C is in execution as a result of determination (Yes at Step S401), then at Step S402, thecontroller 10 determines whether it is during a phone call through the telephone connection established by the outgoing call. When it is during a phone call through the telephone connection established by the outgoing call as a result of determination (Yes at Step S402), then at Step S403, thecontroller 10 acquires the sound pressure level of the sound (sound signal) input to themicrophone 8. - Subsequently, at Step S404, the
controller 10 determines whether the sound pressure level of the sound (sound signal) input to themicrophone 8 is the certain value or higher. When the sound pressure level of the sound (sound signal) input to themicrophone 8 is not the certain value or higher as a result of determination (No at Step S404), thecontroller 10 returns to the processing procedure at Step S402, i.e., to the determination as to whether it is during a phone call through the telephone connection established by the outgoing call. Meanwhile, when the sound pressure level of the sound (sound signal) input to themicrophone 8 is the certain value or higher as a result of determination (Yes at Step S404), then at Step S405, thecontroller 10 determines whether theolfactory sensor 4 c is inactive. - When the
olfactory sensor 4 c is inactive as a result of determination (Yes at Step S405), then at Step S406, thecontroller 10 activates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 28 . Meanwhile, when theolfactory sensor 4 c is not inactive (i.e. when it is active) as a result of determination (No at Step S405), thecontroller 10 directly ends the processing procedure illustrated inFIG. 28 . - When it is not during a phone call through the telephone connection established by the outgoing call as a result of determination at Step S402 (No at Step S402), then at Step S407, the
controller 10 determines whether theolfactory sensor 4 c is active. - When the
olfactory sensor 4 c is active as a result of determination (Yes at Step S407), then at Step S408, thecontroller 10 inactivates theolfactory sensor 4 c and ends the processing procedure illustrated inFIG. 28 . Meanwhile, when theolfactory sensor 4 c is not active (i.e. when it is inactive) as a result of determination (No at Step S407), thecontroller 10 directly ends the processing procedure illustrated inFIG. 28 . - When the
phone call application 9C is not in execution as a result of determination at Step S401 (No at Step S401), then thecontroller 10 proceeds to Step S407, and determines whether theolfactory sensor 4 c is active. -
FIG. 29 is a diagram of a relationship between an execution state of the phone call application according toEmbodiment 6 and an operation state of the olfactory sensor. According to the processing procedure illustrated inFIG. 28 , as illustrated inFIG. 29 , when thephone call application 9C activated in response to the user operation is in execution, themobile phone 1 starts the operation of theolfactory sensor 4 c at a timing when the sound pressure of the sound input to themicrophone 8 reaches the certain value or higher after the phone call is started through the telephone connection established in response to the outgoing call operation performed by the user. In other words, themobile phone 1 starts the operation of theolfactory sensor 4 c at a timing when the speech utterance of the user is detected after the phone call is started. - The
mobile phone 1 does not start the operation of theolfactory sensor 4 c even after the phone call is started through the telephone connection established in response to the outgoing call operation if the sound pressure of the sound input to themicrophone 8 does not reach the certain value or higher. Therefore, according toEmbodiment 6, the power consumed by theolfactory sensor 4 c when the data for the user is measured can be further reduced than that of the example illustrated inEmbodiment 5. Moreover, according toEmbodiment 6, when a target to be measured by theolfactory sensor 4 c is, for example, a concentration of the specific substance contained in the breath of the user, measurement data can be more effectively acquired than that of the example illustrated inEmbodiment 5. In other words, the case where the operation of theolfactory sensor 4 c is started at a timing of the speech utterance of the user can further reduce the wasteful operation time during which the measurement data cannot be obtained, of the operation time of theolfactory sensor 4 c, than that of the case where the operation of theolfactory sensor 4 c is started at a timing of the establishment of the telephone connection. Thus, the measurement data can be effectively acquired. -

Examples of the incoming-call response operation include an operation using, for example, thebutton 3. Examples of the incoming-call response operation include an operation performed by the user to respond to an incoming call on the user interface used to perform an operation for a phone call. The operation performed by the user on the user interface used to perform an operation for a phone call is determined based on the detection result of thetouch screen 21. - The

Moreover, according toEmbodiment 7, when a target to be measured by theolfactory sensor 4 c is, for example, a concentration of the specific substance contained in the breath of the user, measurement data can be effectively acquired. In other words, the case where the operation is started at a timing of the incoming-call response operation can reduce the wasteful operation time during which the measurement data cannot be obtained, of the operation time of theolfactory sensor 4 c, more than that of the case where theolfactory sensor 4 c is operated during the execution of thephone call application 9C. Thus, the measurement data can be effectively acquired. -

In other words, themobile phone 1 starts the operation of theolfactory sensor 4 c at a timing when the speech utterance of the call partner is detected after the phone call is started.

Moreover, according toEmbodiment 8, when a target to be measured by theolfactory sensor 4 c is, for example, a concentration of the specific substance contained in the breath of the user, measurement data can be more effectively acquired than that of the example illustrated inEmbodiment 7. It is assumed that a speech utterance is often started from the call partner when the incoming-call response operation is performed by the user. Based on this assumption, it is considered that, in many cases, the speech utterance by the user is provided after the start of the speech utterance by the call partner. Therefore, the case where the operation of theolfactory sensor 4 c is started at a timing of the detection of the speech utterance of the call partner can further reduce the wasteful operation time during which the measurement data cannot be obtained, of the operation time of theolfactory sensor 4 c, than that of the case where the operation of theolfactory sensor 4 c is started at a timing of the incoming-call response operation. Thus, the measurement data can be effectively acquired. Moreover, inEmbodiment 8, themobile phone 1 may operate theolfactory sensor 4 c at a timing of the speech utterance of the user after the incoming call as explained inEmbodiment 6, for example. - The embodiments have explained a slate type (straight type) mobile phone as an example of the device according to the appended claims; however, the device according to the appended claims is not limited thereto.
